Improvement in grain-binders for harvesters



UNITED STATES ATENT OFFICE.

GEO. W. N. YOST, OF PORT GIBSON, MISSISSIPPI.

Specification forming part of Letters Patent No. 14,036, dated January 1, 1856.

To all whom t't may concern Be it known that I, GEO. W. N. Yos'r, of Port Gibson, Claiborne county, State of Mississippi, have invented a new and useful Improvement in Grain-Harvesters; and Ido hereby declare that the following is a full and exact 4description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure 1 is a plan view. Fig. 2 is a perspective view. Fig. 3 is a front view. Fig. 4 is a section showing the face of the wheel with the cams. Fig. 5 is a section showing the sheaf compressed ready for binding.

In the construction of my invention, Fig. l, A is the driving-wheel; B, the frame; O, the seat; D, the bearings; E, the pinion-shaft; F,

the pin-ions; G, the bearings for pinionshaft,

H, the lever working in cams o; I, the pulley on pinion-shaft; J, beveled Wheel on the end of the main shaft; KK, seats for the binders; L, the cord for operating the slide; M, the rake and compressor a2; a, the stationary compressors; b, the slot cutin the bottom strip for holding the band; c, the grate-bottom, on which the grain falls; N, the guide-pole, d, the upright posts for keeping the grain straight, e, the fingers.

In Fig. 2 A is the driving-Wheel; B, the frame; O, the seats; D, bearings; E, pinionshaft; F, pinions; G, pinion-bearings; H, lever operating in cams o; I, the pulley on pinionshaft; J, the bevel-wheel on the end of the main shaft; K K, seats for the binders; L, cord M, rake and compressor a2; N, the guide pole; a, the stationary compressors; 1),the slot cut in the bottom strip for holding the band; c, the grate-bottom5 d, the upright posts for keeping the grain straight; A2, the small wheel for carrying the machine; e, the fingers.

In Fig. 3P are the pulleys over which the cord passes for sliding the rake and compressor. The other letters ofreference are the same as in Fig. 2.

In Fig. 4 A is the driving-wheel; O, the circular cams; e2, the irregular cams for reversing the motion.

In Fig. 5 B is the frame; a2, the movable compressor; a, the stationary compressor 5 d, the stationary upright posts; g, the cord for cams 0 alternately.-

binding the sheaf; h, the sheaf, M, the rake L, the cord; P, the lower pulley.

In the operation of my invention motion is communicated by means of the driving-wheel. On the face of my driving-wheels are cams o and e2, into which lever H operates, and as the wheel revolves this lever follows the regular rIheirregular cams e2 are for changing the direction of the lever from the inner to the outer` cam, as at o, and vice versa. When the lever His on the outside of cam o the gear-wheel operates on the left pinion and revolves the pulley I, which operates the cord L, attached to slide or rake M, and draws it into the compressed position as in Fig. 5, letters a?, a, and h. As the lever passes over the outer irregular cam @Zit is changed to the inner cam 0 and'throws the righthand pinion into gear, and by means of the cord, as before, draws the rake in a compressed form, as above, on the other end of the machine, ready for binding. 'lhe lever H in passing over the inner irregular cam changes the levers H to the outer cam o again. I may use a springin the rear of the stationary compressors a to allow them to yield.

A man or boy is seated on each ofthe seats K for binding. He is prepared with bauds of cord, which have a knot on the end, and as the rake or compressor slides back he places a cord in slot 0 and brings the other end under the seat, where it is held until thesheaf is compressed, when he brings the two ends up and ties the band in time for the compressor to let it go, when the sheai is removed by him and the same operation is performed at the other end, as beforedescribed.

Having thus fully described the construction and operation of my invention, what I claim as new, and desire to secure by Letters Patent, is-

'.Ihe double reciprocating compressor a2 for gathering and compressing the grain against the stationary compressors a a, ready for binding, operating and operated substantially as described.
